Well there are actually rules about whether you are considered dependent or not partly based on how much money your dad is giving you and in what form. All students (who enroll at least half-time) can take out unsubsized stafford loans if they fill out the FAFSA. I believe FAFSA considers all graduate students (including law) independent from their parents, but either way you still as a full-time student can take out those loans. What you might gain from filling out the FAFSA is need-based grants and/or subsidized stafford loans. But some schools also make you fill out Need Access to get that part, which your parents have to fill out as well (even noncustodial sometimes depending on the school's policy). So there you may not qualify for any need-based aid. Still there are private loans as well as unsubsidized stafford loans to help cover tuition.
